Is Granite Sedimentary

Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.

Is granite sedimentary.

Granite is an example of a felsic intrusive rock while gabbro and diabase are examples of mafic intrusive rocks. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. What granite means. I type igneous granites appear to arise from the melting of preexisting igneous rocks s type sedimentary granites from melted sedimentary rocks or their metamorphic equivalents in both cases.

Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Students of granites classify them in three or four categories. Sedimentary rocks are formed by the gradual consolidation of organic or inorganic solid fragments carried by suspended in or dropped by wind water or ice and deposited horizontally in layers. Essentially they are comprised of layer upon layer of sediment easy to remember sediment sedimentary build up over time.

Sedimentary rocks unlike the igneous rock granite form on both the earth s surface and underwater. It forms from the slow crystallization of magma below earth s surface. The definition of granite varies a geologist might define granite as a coarse grained quartz and feldspar bearing igneous rock that is made up entirely of crystals. It erodes into sediment and then gets compressed into a sedimentary rock.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Tile made from it is quite dense with a strength similar to porcelain says dave gobis executive director of the ceramic tile education foundation. However in the dimension stone trade the word granite is used for any feldspar bearing rock with interlocking crystals that are large enough to be seen with the unaided eye. M type mantle granites are rarer and are thought to have evolved directly from deeper melts in the mantle.

As an igneous rock granite is formed under very high heat and has a crystalline structure instead of a layered structure like sedimentary rock. Strictly speaking granite is an. The sedimentary rock becomes metamorphic with heat and pressure.
